Abstract

High levels of microbial contamination, commonly found in animal origin foods and food processing environments, are able to hinder the growth in these products. In some contexts where lactic acid bacteria (LAB) are the normal dominant microbiota, such as in fermented food, Staphylococcus coagulase positive (SCP) colonises, persists and produces food poisoning. With the aim of verifying the interference of autochthonous microbiota encountered in Curd cheese over the presence of Staphylococcus aureus, 64 samples from 16 dairy were submitted to microbiological analysis to determine the levels of Microorganisms aerobes mesophilics (MAM), LAB and SCP. The results showed that the indigenous microbiota of the samples did not lead to inadequate growth, development and isolation of SCP, since this pathogen was detected even in samples with high levels of counts of AM and BAL.
